Joshua 23:6–13

⁶And be ye very courageous to keep and to do all that is written in the book of the law of Moses, that ye turn not aside therefrom to the right hand or to the left; ⁷that ye enter not among these nations, these that remain among you; and ye shall make no mention of the name of their gods, nor cause to swear by them, neither serve them, nor bow yourselves unto them; ⁸but ye shall cleave unto Jehovah your God, as ye have done unto this day. ⁹For Jehovah hath dispossessed from before you great and strong nations; and as to you, no man hath been able to stand before you unto this day. ¹⁰One man of you chaseth a thousand; for Jehovah your God, he it is that fighteth for you, as he hath said unto you.

¹¹Take great heed therefore unto your souls, that ye love Jehovah your God. ¹²For if ye in any wise go back, and cleave unto the residue of these nations, these that remain among you, and make marriages with them, and come in unto them and they unto you: ¹³know for a certainty that Jehovah your God will no more dispossess these nations from before you, and they shall be snares and traps unto you, and scourges in your sides, and thorns in your eyes, until ye perish from off this good land which Jehovah your God hath given you.
